The refined and simplified title is: LiftMaster 850LM Universal Receiver for Gate and Garage Door Openers

The Universal Receiver and accompanying remote controls, designed for both gated communities and commercial buildings, feature Security+ 2.0 technology. The encrypted signal of this technology safeguards property access with extended range. Property managers can manage and support multiple access points, such as the main gate, tenant and visitor doors, commercial doors, and even parking entrances, all with a single remote control solution that offers superior range and security.

This single transmitter solution provides convenient access to gated communities, industrial facilities, and commercial sites. Three channels offer expanded remote control capacity: Channel 1 - 50 remotes, Channel 2 - 20 remotes, and Channel 3 - 20 remotes. Multiple remote control options are available to securely access these areas from the safety and convenience of a vehicle.

The compact design of the receiver fits most gate and commercial door operators, and a weather-resistant version (model 860LM) is available. The receiver is compatible with 811LM, 813LM, and all MAX remote controls. It operates on 12-24VDC or 12-24VAC and features Relay Outputs with 1 FORM C and 2 FORM A relays. The Narrow-band Security+ 2.0 Rolling Code and Encrypted DIP technology ensures operational temperatures from -35 to 65 degrees Celsius and storage temperatures from -40 to 85 degrees Celsius.
